Senate Democrats likely will stall on whomever Trump nominates while Republican senators such as Susan Collins of ME and Lindsey Graham of SC have voiced concerns over nominating someone to the position who works in a partisan environment. Cornyn, the Senate majority whip, is the second-highest ranking Republican in the chamber, meaning his possible appointment would trigger political moves both there and in his home state of Texas.
Asked about the White House's shifting explanations for Comey's firing, Cornyn said he still backed the President's decision and supported the initial reasoning behind the firing - that Comey mishandled the Clinton email investigation.
Cornyn's credentials include having served on the senate judiciary committee and as attorney general of Texas.
Cornyn may have already made the short list.
"I have called repeatedly on the attorney general to appoint a special counsel to fully and fairly conduct the investigation", Cornyn said on the Senate floor in March 2016.
"John Cornyn is a wonderful man", Graham said. Among them are Senator John Cornyn of Texas, the No. 2 Republican in the chamber and Representative Trey Gowdy of SC, who led the most recent congressional investigation into the Benghazi attacks.
That decision followed clashes over President Donald Trump, and the cancellation of an appearance by right-wing provocateur Milo Yiannopoulos amid destructive student disturbances.

John Cornyn to lead the Federal Bureau of Investigation, it's not a given that the Texan would sail through the confirmation process in his own chamber. Trump also is looking at former Rep.
Adam Lee, the special agent in charge of the FBI's Richmond, Va., office, was the latest to join a roster that is expected to balloon to as many as a dozen names.
"It's now time to pick somebody that comes from within the ranks or is of such reputation that has no political background at all", Graham said.
